Government Help for Energy-Efficient Living
Great British Insulation Scheme (GBIS)
The Great British Insulation Scheme is a government initiative in the UK aimed at improving energy efficiency and reducing carbon emissions in homes.
The cost of keeping our homes warm has risen significantly, leaving many UK households searching for solutions that are both affordable and energy-efficient. The Great British Insulation Scheme is one such government initiative, designed to provide insulation upgrades to help reduce energy bills and improve home comfort for eligible households. GBIS aims to support homes that need it most, especially those with low energy performance ratings or higher heating costs.
The GBIS grant scheme is run by Ofgem and funded by energy suppliers in the UK. It aims to provide individual insulation solutions like loft, cavity wall, or solid wall insulation to households that qualify under specific eligibility requirements. This grant supports both low-income households and general groups through a fair and structured process that ensures impactful savings and long-term comfort.
What is the GBIS Grant?
The GBIS grant is a government-funded support scheme under which energy suppliers must deliver home insulation upgrades to help households improve energy efficiency and reduce heating bills. This scheme was introduced to build upon the government’s wider Energy Company Obligation (ECO) programme and extends support to a broader set of households than previous schemes.
The grant covers the full or partial cost of installing a single insulation measure, which depends on the applicant’s eligibility. GBIS grants are focused on quick, effective upgrades that bring impactful results.
Who is Considered Eligible?
The GBIS grant scheme has two distinct eligibility groups:
- General Group: This group includes homeowners or tenants living in properties within council tax bands A to D in England (or A to E in Scotland and Wales) that have a valid Energy Performance Certificate (EPC) with a rating between D and G. This group is not income-tested.
- Low-Income Group: Households that are receiving means-tested benefits, including Universal Credit or Income Support. This group can also receive heating controls where needed, in addition to insulation.
Private renters can also benefit from GBIS, provided their landlord consents to the work.
What Does the GBIS Grant Cover?
The GBIS grant covers the cost of installing two insulation measures in a household under certain circumstances, rather than just one insulation measure per property. These can include:
- Loft insulation
- Pitched roof insulation
- Flat roof insulation
- Cavity wall insulation
- Solid wall insulation (internal or external)
- Underfloor insulation
- Park home insulation
- Room-in-roof insulation
The type of insulation offered depends on the needs of the property, based on a professional assessment carried out before installation.
How the Scheme Works
Once a household is considered eligible, the process moves swiftly through the following steps:
- Assessment: A retrofit assessor visits the property to confirm the EPC rating and identify the most suitable insulation measure.
- Installation: A TrustMark-registered installer then carries out the work in line with government standards.
- Supplier Reporting: Energy suppliers record the completed work and count it toward their annual target obligations.
Progress and Impact So Far
As of the May 2025 statistical release, the GBIS grant scheme is steadily progressing with figures showing continued installations across England, Scotland, and Wales.
As of the end of March 2025, 76,900 measures have been implemented in 60,600 households since the inception of GBIS. In March 2025, 4,900 families had 6,500 measures installed. In comparison to February 2025, this represented a 14% increase in measure delivery.
Key Benefits of the GBIS Grant Scheme
- Reduced energy bills: Better insulation means less heat loss, which leads to noticeable savings.
- Improved living comfort: Homes stay warmer in winter and cooler in summer.
- Support for vulnerable groups: Low-income households receive essential support without the burden of cost.
- Contribution to climate goals: Energy-efficient homes play a vital role in reducing national emissions.
